Merge branch 'release-3.2.2'

- Python gotcha fixes
  - Fixed issues with mallocp segfaulting from Python
  - Fixed storage merge() segfaulting
- New Python tools submodule (timemory.tools)
  - tools.function_wrappers combines {start,stop}_{mpip,ompt,ncclp,mallocp}
    into one configurable handle and provides decorator + context-manager features
- New Python functions which are used within tools.function_wrappers
  - timemory.start_function_wrappers
  - timemory.stop_function_wrappers
- Fixed timemory-python-line-profiler script calling timemory.profiler
- API change in ring_buffer template
  - read/write member functions return pointer to object read/written to
    instead of bytes
- API change in storage and tsettings
  - Classes are declared as final to optimize any vtable calls
- Removed runtime_configurable restriction for do_enumerator_generate
  - This enables user_bundles to be used again in Python
- Added operation::python_class_name
- Updated examples:
  - ex_python_bindings (and libex_python_bindings)
- Fix to get_hash_identifier
- Removed concurrency comparison when generating a diff b/t two runs
- Fixed issues with popen.cpp guarding with TIMEMORY_WINDOWS but never defined
